Kickr V6 direct connection option disappeared from loin in options

I recently got a Kickr V6 which had options to connect to the game via ANT+, Blue tooth and direct wired connection. This is built in direct connection was excellent resulting in almost instant real life and game power changes which is great for riding and exactly what you want for racing.

I got the Kickr 6 in February. The option to direct connect worked for about a week and now that option to connect no longer appears on the pairing options screen. I have turned on and off everything and checked wire is connected everywhere (it is).

Can you help, please? One of the selling points of the V6 is the direct connect.

Many thanks,

Does Direct Connect appear in the Wahoo Fitness app, when Zwift is not running?
